General description

Sodium peroxide (Sodium superoxide) has been synthesized by reacting sodium atoms and oxygen molecules at high dilution in argon. Its IR spectral studies have been reported.[1] It is a strong oxidizing agent.[2]

Application

Sodium peroxide may be used for the isotope dilution inductively coupled plasma mass spectrometric quantification of Ru, Pd, Ir and Pt in various geological samples.[3] It may be employed for the inductively coupled plasma mass spectrometric quantification of rare earth elements (such as Y, Th, Zr, Hf, Nb and Ta) in geological reference materials.[4]
